snapd is not in the official repositories, and ADR 0205's archive does not
fit a daemon with setuid helpers, so the module declares nothing until
research 027 question 1 (P2) builds it into the mesh's own repository. Not
even its units: on the laptop they do not exist, and the module would fail
there.
Ten Go tools that work wherever snapd is installed and say so where it is
not: status (with AppArmor's absence from the kernel named), list, info,
updates, disk usage with the disabled revisions' share, services, changes,
and install, remove and refresh through sudo -n with --no-wait, answering
snapd's change id.
